Illinois is moving forward with the construction of the 128-acre Illinois Quantum & Microelectronics Park (IQMP) on Chicago’s Southeast Side, a project anchored by the tech firm PsiQuantum and designed to be the centerpiece of a broader $9 billion “Quantum Shore” development. While state officials, including Governor JB Pritzker, and developer Related Midwest promise a massive economic engine for a historically underserved area, the project is currently defined by a significant transparency gap regarding its environmental impact. Specifically, developers have yet to release a quantified, authoritative gallons-per-day estimate for the campus’s water use. Although project materials claim the facility will utilize closed-loop cooling and advanced wastewater recycling to minimize its footprint, local residents and investigative reports highlight a lack of independent verification and specific data on the “ultrapure” water requirements necessary for quantum chip fabrication.
The Vision for Quantum Shore
The IQMP is not just a single office building; it is a purpose-built campus intended to house the future of American computing. PsiQuantum, the anchor tenant, has already begun site work following significant private and public funding. The site, located on the former US Steel South Works land, is part of a strategic push to make Chicago a global hub for quantum and microelectronics.
Governor JB Pritzker has been a vocal supporter, framing the project as a generational opportunity. “This isn’t just about jobs; it’s about Illinois leading the next industrial revolution,” Pritzker noted during a recent briefing on the site’s development. “We are building the infrastructure for the 21st century right here on the lakefront.”
The Water Debate: Closed-Loops and Unknowns
The most contentious issue surrounding the IQMP is its relationship with Lake Michigan. Because microelectronics and quantum fabrication require “ultrapure water”—water treated to remove nearly all minerals and impurities—residents are concerned about the sheer volume of freshwater needed.
Developers and IQMP officials have released an FAQ stating that the campus will aim to operate with closed-loop systems. In a closed-loop system, water is recycled through the facility multiple times rather than being discharged and replaced constantly.
Technical Reality of Closed-Loop Systems:
Recirculation: Reduces the need for continuous freshwater withdrawals.
Make-up Water: All systems lose water through evaporation or “blowdown” (removing mineral buildup), requiring a steady supply of fresh “make-up” water.
Ultrapure Requirements: Creating ultrapure water for chip washing involves a high-rejection process that can result in significant wastewater.
Despite these technical claims, an investigative report by the Illinois Answers Project flagged that officials have not provided a sitewide projection for daily water consumption. This lack of data has fueled fears that the campus could eventually burden municipal treatment systems or increase total withdrawals from the lake.
Expert and Community Perspectives
Community advocates argue that “trust us” is not a sufficient environmental policy. “We’ve seen industrial promises made to the Southeast Side before,” says Ana Guajardo, a local community organizer. “We want to see the numbers. How many millions of gallons are we talking about? Where is the water going after they use it?”
This skepticism has led to a growing demand for a binding Community Benefits Agreement (CBA). A CBA would legally require the developers to guarantee local hiring, prevent displacement of current residents, and adhere to strict, transparent environmental safeguards.
On the other side, supporters point to the environmental remediation already underway. Related Midwest has enrolled the property in state programs to clean up decades of industrial contamination left by the steel industry. “This project is actually cleaning up a site that has been a blemish on the lakefront for years,” says a spokesperson for the development team. “We are following every Illinois EPA guideline to ensure a safe and sustainable campus.”
Scale and Strategic Importance
While the IQMP’s water needs are expected to be smaller than those of a “mega-fab” semiconductor plant, the presence of federal partners like DARPA underscores the site’s strategic importance. The federal government views quantum computing as a matter of national security, which brings a level of scrutiny—and funding—that few other local developments receive.
| Stakeholder | Role in the Project |
| PsiQuantum | Anchor tenant; building the world’s first utility-scale quantum computer. |
| Related Midwest | Primary developer responsible for the 128-acre master plan. |
| State of Illinois | Providing hundreds of millions in incentives and infrastructure support. |
| DARPA | Federal partner interested in the national security applications of the tech. |
What Residents Should Watch
As construction proceeds, the debate will likely shift from broad promises to specific permits. Readers should monitor whether the Illinois EPA releases detailed operational metrics or if the developers finally publish a quantified water-use study.
The “Quantum Shore” has the potential to redefine Chicago’s economic landscape, but for the residents of the Southeast Side, the true cost of that progress remains a question written in the water. Without a binding agreement and transparent data, the gap between the project’s high-tech future and its environmental reality will continue to be a point of friction.
